Text::Levenshtein is an implementation of the Levenshtein edit distance in Perl.
A good point to start is:
See also Text::WagnerFischer on CPAN for a configurable edit distance.
PREREQUISITES
This suite requires Perl 5; I tested it only under Perl 5.6.
Text::Levenshtein does not use any nonstandard modules.
INSTALLATION
You install Text::Levenshtein by running these commands in the *nix environment:
perl Makefile.PL
make
make test (optional)
make install
To install Text::Levenshtein in the Win32 environment, use nmake instead of make.
nmake is available for free (in a self extracting executable):
After download and inflate, put nmake.exe and nmake.err in c:\windows\command .

POD format documentation is included in Levenshtein.pm.
POD is readable with the command:
